Description
Open Frame – Expert Packing Puzzle
Open Frame is a packing puzzle designed by Lucie Pauwels and produced by Pelikan Puzzles. Single blocks at the center of each side create an unusually open anti-slide frame.
Fit all nine pieces into the seven-by-seven square and make sure none can slide out through an edge. Completing the square without satisfying that movement condition is not the final solution.
Specifications:
- Designer: Lucie Pauwels
- Producer: Pelikan Puzzles
- Difficulty Level: Expert
- Puzzle Type: Packing Puzzle
- Material: Maple, Zebrano, Ash, Purpleheart, Wenge, American Walnut, Jatoba, Acacia, Padauk and Oak
- Dimensions: 109 mm × 109 mm × 20 mm (approximately 4.29 in × 4.29 in × 0.79 in)
- Components: 9 puzzle pieces and a board with four fixed edge blocks
- Objective: Fill the square so no piece can slide sideways out.
Features:
- Open Boundary: A fixed block at each side’s center replaces a continuous surrounding frame.
- Anti-Slide Condition: The pieces must prevent one another from escaping sideways.
- Nine-Piece Packing: All nine shapes are used to complete the square.
- One Qualifying Solution: Of the 15 reported square assemblies, only one satisfies the anti-slide rule.
Why You'll Enjoy It:
Open Frame suits solvers who enjoy testing the stability of an entire arrangement rather than just filling gaps. Its open boundary makes the movement constraint central to every placement.
